What about teas?

Bringing in any other form of calories, vitamins, minerals or chemicals pretty much defeats the purpose of the cleanse.
I understand there are a lot of people that drink teas like smooth move, either because the SWF (Salt-Water-Flush) doesn't work for them or to aid it.
Yesterday I was far from a lemon and some maple syrup on a five hour drive and broke down and had 100% orange juice. I knew it was not on the plan, but thought it best of the options since it's used to come out of the detox. But even that was a diversion from the program and may have had some effects. Of course, I figured it was better than quitting all together.
I would definitely keep soda out, maybe trade the teas for coffee.
I think that cutting out bad food and replacing it with a lemonade meal, will do good things for you. But from what I read, to really serve it's purpose, it's all or nothing.
Anyone have advice for teas allowed?
